We’ve been driving to Jericho since 1984, long before the Long Island Expressway widened and back when North Broadway was still two lanes in spots. Our Chimney Cap & Crown team knows these chimneys. The 1950s and 1960s masonry you see from Cantiague Lane to the Jericho Turnpike corridor was built for a different era of heating - oil-fired boilers with oversized flues - and that history matters when we’re fitting a new cap or rebuilding a crown today. We’re usually on-site in Jericho within 24 to 48 hours of your call.
Why Hearthstone Chimney Co. of New York City Is Jericho’s Preferred Chimney Cap & Crown Company
Jericho homeowners don’t call us once. They call us back when their sister in Syosset needs a sweep, or when their neighbor on Woodbury Road asks who fixed their crown last spring. That repeat business is how we’ve stayed in operation for over 42 years - not through coupons, but through jobs done right and a 90-Day Done Right Promise backed in writing with no arguing.
Our reviews from Jericho customers mention the same things: Frank Calucci and his team show up when they say, explain what they found with photos the homeowner can actually see, and leave a written verdict in plain English. No vague warnings. No pressure to buy.
Response time to Jericho averages same-day or next-day for cap and crown emergencies - a loose or missing cap after a nor’easter, a crown crack that’s opened after another freeze-thaw cycle. We keep DuraFlex, HeatShield, and Gelco materials stocked for Nassau County work, so we’re not ordering parts while your chimney takes on water.
We also understand the local permitting landscape. Jericho falls under Nassau County building codes, and any crown rebuild involving structural mortar work requires proper documentation. We’ve filed enough of these to know the inspectors by name. That saves you delays.
Our Chimney Cap & Crown Services in Jericho
Custom Cap Installation
Jericho’s split-levels and raised ranches often have unusual flue configurations - two flues of different diameters, or a single large flue originally sized for oil that now needs reduction for gas. A box-store cap won’t seat properly on these setups. We measure on-site and order custom caps from Copperfield or Gelco that fit your exact flue arrangement. On a recent job near the Jericho Public Library, we fabricated a custom stainless cap for a 1964 Colonial with a 13×17 inch flue cluster that no standard size would cover. Done right - and we stand behind it.
Cap Replacement
Caps rust, blow off in wind, or get damaged by falling branches. In Jericho, we also see caps that were never correct to begin with: too small for the flue, missing a spark arrestor, or installed without proper mounting brackets for our coastal wind loads. We replace with professional-grade caps sized to your flue, your crown condition, and your exposure to salt-laden air off Long Island Sound. Most cap replacements in Jericho run $280-$450 installed, and we complete them in one visit.
Crown Repair
The crown is the concrete or mortar slab that seals the top of your chimney, sloped to shed water. Jericho’s original crowns from the 1950s and 1960s are now 60 to 70 years old, well past the 50-year typical service life of exterior mortar in our climate. Salt air, freeze-thaw cycling, and the thermal stress of mismatched gas flues have left many crowns cracked, spalled, or porous. We repair with crown-specific mortar mixes or apply a full rebuild when the structure is too far gone. A typical crown repair in Jericho runs $420-$680; full rebuilds range $740-$1,200 depending on chimney size and access.
Crown Coating
For crowns with minor cracking or surface erosion but sound structure, we apply a flexible crown coating - typically HeatShield or a comparable professional-grade product - that seals hairline cracks and restores water-shedding slope. This is preventive maintenance that can add a decade of service life to a Jericho crown that’s showing early wear but doesn’t yet need rebuild. Crown coating in Jericho typically costs $340-$520. We recommend it for any crown over 50 years old that’s still structurally sound, which describes a significant portion of the housing stock between Jericho Turnpike and the Northern State Parkway.
Multi-Flue Cap Systems
Many Jericho homes have two flues - one for the original oil boiler, one for the fireplace - but no unified cap system. Water enters at the gap between flues, freezes, and opens cracks in the crown below. We install multi-flue caps from Copperfield or Olympia Chimney that cover the entire chimney top with a single sloped lid, proper overhang, and screened sides. These are especially valuable for Jericho’s converted gas homes, where one flue may be active and the other “retired” but still vulnerable to moisture intrusion.

Common Chimney Cap & Crown Problems We See in Jericho Homes
- Salt-laden wind damage to crowns. Jericho sits 10-12 miles from Long Island Sound, and prevailing winds carry measurable salt content that degrades mortar joints and chimney crowns on exposed masonry. We see accelerated spalling on homes near open fields or taller tree lines that don’t block the wind. Yearly inspection catches this before rebuild is necessary.
- Condensation damage from oil-to-gas conversion. Most Jericho chimneys were built for oil appliances with oversized flues. When homeowners switched to gas without relining to the correct diameter, the resulting condensation inside the flue attacks the crown from below. A standard cap won’t fix this - the flue needs assessment and often resizing.
- Multi-flue water intrusion at the junction. Split-levels and raised ranches with separate boiler and fireplace flues often lack a unified cap. Rain enters the gap between flues, pools on the crown, and freezes. We’ve rebuilt crowns on North Broadway and Cantiague Lane where this exact pattern had gone unaddressed for fifteen years.
- “Retired” flues silently deteriorating. A pattern local sweeps learn quickly: Jericho homeowners who switched to gas heat kept their old oversized oil-flue chimney intact but stopped using it. Without proper capping and maintenance, these flues accumulated moisture damage, efflorescence, and liner cracks while the owner assumed the chimney was no longer their concern. The crown doesn’t know it’s “retired.”

We provide no-hassle upfront pricing before any work begins - the number on the estimate is the number on the invoice. Free estimates. Call (855) 950-3861.
On a split-level home on North Broadway, we replaced a crumbling brick crown and installed a custom copper multi-flue cap from Copperfield. The homeowner’s original 1960s crown had spalled from salt-laden winds off the Sound, and the cap’s spark arrestor kept out the squirrels that had colonized both flues. That’s the kind of job we measure carefully and price once.

FAQs - Chimney Cap & Crown in Jericho
Yes, almost certainly. A 1962 crown in Jericho has endured 60+ years of Long Island freeze-thaw cycles and salt-laden winds, and the original mortar mix was never formulated for today’s thermal stress. We inspect crowns with level-2 camera equipment and provide photos you can see, along with a plain-English verdict. If the crown is cracked or spalled, water is entering your chimney structure every rainfall. Call (855) 950-3861 for a free inspection - estimates are free.
Because the chimney doesn’t know it’s “retired.” Without proper capping, rain enters the flue, freezes in the crown, and opens cracks. Meanwhile, the oversized flue designed for oil creates condensation that attacks mortar from inside. We’ve found “retired” flues in Jericho with severe liner damage that the homeowner never suspected. The crown is your chimney’s roof - abandoned or not, it needs maintenance. Call for an assessment.
We can. Gelco and Copperfield offer low-profile and traditional designs in painted steel, stainless, or copper that complement Jericho’s 1950s-1960s architecture without looking like an afterthought. We show you options on-site and measure for proper proportion to your chimney’s footprint. A cap that fits well looks right.
Annually, without exception. Jericho’s climate - repeated freeze-thaw cycling, salt air, and the thermal mismatch of converted gas flues - accelerates crown deterioration beyond what inland or newer construction experiences. We recommend a level-2 inspection every year that includes crown photography and a written condition report. Catching crown damage early means coating instead of rebuild, saving hundreds of dollars.
In most Jericho homes with two flues, yes. A single cap per flue leaves a gap where water enters, freezes, and damages the crown between them. A multi-flue cap covers the entire chimney top with proper slope and overhang, protecting both flues and the crown structure. We assess your flue spacing and recommend the right configuration. Most Jericho installations of this type run $620-$980. Call (855) 950-3861 for exact sizing and pricing - estimates are free.
